Architectural bronze, also known as C38500, C385 or C38000, is used in both interior and exterior design applications and is commonly used for window and door bronze casements as well as industrial hardware. Contrary to its name, C385 belongs to the brass family rather than bronze but the interchangeable use of the terms stems from their shared metal classification – copper. These two metals have distinct differences in their chemical composition and properties which set them apart.

This decorative metal has a rich history dating back centuries, with its use in architecture and design spanning various civilizations. In ancient times, the Egyptians and Greeks utilised bronze alloys for their aesthetic finishes in temples, statues, and monumental structures. Today it is still widely used in contemporary construction and design projects, contributing to the creation of aesthetically pleasing and durable elements such as ornamental features, exterior cladding, and various structural details.

The chemical composition of C38500 typically includes the following – Copper(Cu) 55% to 65%, lead (Pb) 2.3% to 3.5% and iron (Fe) a maximum of 0.35% and small amounts of zinc. C38000 is composed of 55-60% copper (Cu), 1.5-2.5% lead, 0.30% tin, 0.50% aluminium and 0.35% iron as well as trace quantities of other elements.

Fabrication Properties

C38500 has an excellent capacity for being hot-formed making it ideal for soldering. It has a machinability rating of 90 and is good for brazing and fair butt welding capabilities. C38500 has a poor capacity for cold forming and is not recommended for spot welding, seam welding, arc welding or Oxyacetylene welding. The common fabrication processes for this material include hot forging and pressing, hot forming and bending as well as machining.

The long-term stability and strength of this ornamental metal are due to its superior corrosion resistance while its physical appeal is enhanced over time due to the natural patination process. This makes it the perfect choice for building work and industrial applications where a hard-wearing architectural metal is required.
